Ink Bleeds Through Wallpaper!

I am stripping off this wallpaper, and will repaper the room tomorrow. When this was originally hung, someone must have written on either the wall or the back of the wallpaper in ink. And the ink is doing what ink does – bleeding through to the surface. Solid vinyl papers are particularly bad about letting ink work its way through.

Other materials will to this, too – rust, blood, oil or grease, food stains. Such stains should be cut out of the wall and patched and then sealed (KILZ Original is super for this), or, at minimum, sealed. And if you have to write on the wall (as I do when marking measurements, etc.) always use a pencil, NEVER an ink pen or grease pencil.
